This paper presents a novel shared-aperture smartphone antenna for sub-6 GHz and millimeter-wave (mmWave) bands.The proposed 4NN antenna module comprises a four-element mmWave patch antenna array integrated into a wideband sub-6 GHz slot antenna.The mmWave antenna covers the frequency band 26.5–29.5 GHz with isolation over 16 dB, and the sub

Background: Since the use of ionizing radiation in the health sector has been expanding, it is critical for healthcare professionals to be trained and appropriately aware of ionizing radiation in order to protect themselves and their patients from its adverse effects.Despite this, radiation awareness among nurses is a poorly researched topic.This s

The proposed protocol features reliable and fast image transmission while periodically transmitting scalar data without interruption by allowing two networks, a LoRa network and a wireless sensor network, with different transmission characteristics to cooperate.It adopts the RT-LoRa protocol for periodic scalar data transmission and uses a WSN-base
